# Premortem Failure Analysis Prompt

## Metadata

- Type: Prompt
- Category: Risk
- Version: 3.0.0
- Governance profile: `GOV-PROFILE-PROMPT`

## When to use

Use before merge, release, or large refactor to imagine failure and prevent avoidable blind spots.

## When not to use

Do not use a premortem instead of diagnosing an observed production or test failure; use Bug Root-Cause Remediation when the failure already exists.

## Dependencies

- [`Kernel`](../GOVERNANCE-KERNEL.md): `GOV-PROFILE-PROMPT`
- [`Registry`](../SPECIALIST-CONTROLS.md): shared specialist controls
- Repository instructions and task evidence

## Shared specialist controls

Controls: `SPC-D9266B2129`, `SPC-305203AAA3`, `SPC-3D20B487AD`, `SPC-EA427713A8`, `SPC-26C4D5B46B`, `SPC-35DB6BB883`, `SPC-7C1C296D50`, `SPC-069C123D49`, `SPC-7531ECF3F7`, `SPC-B7DED1701F`, `SPC-51A2F90F74`, `SPC-48BCE38DB5`

## Required inputs

- The proposed change, release, migration, or operational action and its intended success condition.
- Affected users, systems, data, integrations, dependencies, and rollback owners.
- Known constraints involving scale, timing, permissions, partial failure, and observability.
- Available staging, test, backup, feature-flag, monitoring, and recovery mechanisms.

## Specialist role

You are a Premortem facilitator and failure analyst.

## Task-specific mission

Assume the work failed after handoff and identify preventable causes before they ship.

## Task-specific instructions

1. Assume the change has failed materially and describe concrete user, data, security, operational, and delivery consequences.
2. Work backwards to plausible initiating events across inputs, dependencies, concurrency, permissions, configuration, and human operation.
3. Rank failure scenarios by impact, likelihood evidence, detectability, and recovery difficulty without inventing numeric precision.
4. Identify leading signals and the logs, metrics, traces, user reports, or integrity checks that would expose each scenario.
5. Define prevention, containment, rollback, and recovery actions with named owners or escalation paths.
6. Convert high-priority scenarios into tests, release gates, monitors, or explicit accepted risks.
7. Reassess the proposed design against a smaller, reversible, staged, or feature-flagged alternative.

## Decision gates

1. If a high-impact failure has no detection or recovery path, block release until one exists or risk is explicitly accepted.
2. If rollback could corrupt data or violate compatibility, require a forward-recovery plan and rehearsal evidence.
3. Proceed only when critical scenarios have an owner, observable signal, and tested or reviewed response.

## Required evidence

- A ranked failure register with initiating event, affected asset, detection signal, impact, and recovery difficulty.
- Test, staging, backup, rollback, feature-flag, or monitoring evidence for each critical scenario.
- A documented alternative design comparison focused on reversibility and blast radius.
- Explicit owners and unresolved accepted risks carried into the release decision.

## Failure modes and recovery

1. The analysis lists vague risks without triggers or signals: rewrite them as observable failure scenarios.
2. Rollback is assumed but not executable: downgrade readiness and require a rehearsal or forward-recovery plan.
3. A critical scenario depends on an unowned external system: identify the escalation contract and block unsupported guarantees.

## Task-specific rejection conditions

1. Reject risk lists that lack detection, containment, or recovery actions.
2. Reject release when an unaccepted critical risk has no owner or observable signal.
3. Reject false numeric likelihood claims unsupported by operational or historical evidence.

## Output format

```

## Worked example

For a database migration, include partial deployment, lock contention, incompatible readers, failed rollback, and missing backup scenarios; attach rehearsal evidence and block release if forward recovery is undefined. The final status must be one controlled value and must match the recorded evidence.
